- CALENDAR.

Application led May 8,

To all whom t may concer/n: Y

. Be it known that I, CLARA L. Coon, a citizen of the United States, lresiding at El Monte, in the countyA of Los Angeles and State of California, have invented a new and useful Calendar, of which the followin is a specification.

his invention relates. to a calendar which may be used for ascertaining the dayjof the week for anyA predetermined date.

In carrying out this invention I provide a condensed calendar chart'by which one can easily and quickly iascertain on what day of the week the rst day of any month occurs within a required period as 100 years more or less.

An object is to provide a mechanical device that canbe easily adjusted to exhibit a full ,calendar for any month inany year covered by the chart. j

Other objects are cheapness, easeof construction and operation, and practieability for every dayuse'. l

.An object of the invention is to provide a simple method for ascertainingl dates of days in any predeterminedyear.

In carrying out Vthel invention I provide a frame having on its rear side a chart of the character stated,v and Vhaving on its frent side aslide-way marked along its edges-,with the days of the week equally spaced apart and a slide provided with the numbers of lan 4.

Fig. 4 is a' front view of the calendar, adjusted for the month of January in the years 1919, 1930, 1936, 1941, 1947, 1958, 1964, 1969, 1975 and other years.

`Fig. 5 is aview analogous to Fig. leshowi922. serial no. 559,277'.

ing the calendar a'djustedfor the month of February in lleap years 1920, 1948 and 1976.

Fig. 6 isa View of one side of the slide used for designating the -various months.

The frame or main body of the calendar is formed vof front land reary rectangular pieces l1, 2, whichy may be of an suitable material, such assheet-metal, car -board or I the like,.joined by any suitable means' as the clipsl 3v; or suchinain body mayy be formed from a single piece folded upon it-v self, as shown at 4, inFig.` 3. .The front piece 1 yof the calendar has an aperture Y' of suitable size to disclose the name dof a predetermined month. Said namesG vare printed on a month designating slide v7 which is adapted to slide from'endlto `end 4 between the front land back pie'cesl, 2.of

the calendar in such a manner that only the name of the predetermined month Will be presented to view.' Q A thumb piece 8 is pro .yided at the top lineofsaid slide 7 to faoilitate movement thereof and hookst10, l11 i are provided at the top 9 of the slide 7,`fa11d rest onthe pieces 1, 2, to support the Amonth designating slide ,.7 in the bodyA of the calendar, said slide is in the present instance reversible andV containson one side the naines of the'iirst six months of thevyear, an'don the, other side the names of the remaining six months. Itis understood that.

the 'same may be so constructed that all the names-of the Inonthsvvill bevon/onesid'e of the slide. Underneath the naine' ofeach month there is applied a mark 12 showing the number' of days in said lino'nth. The

month of February appearsy tWicel to accom# modatev both thecommo'n and leapfyear, thereby Vnecessitating seven ynaines onvone side of ther month indicating slide 7 Ior thirteen names altogether. y 'j A day of the month indicating slide v13 is provided-at its top'and ybottom respectively with thenumerals arepresenting'the numbers of days of the month and this slide is adapted to slidel in a slide-way 131 formed in the front piece 1 and said numerals Zi. are

visible through an aperture 14. A'thumbpiece 15 provides convenient means for moving said slide 13. i The top and bottom relspectively of the v`aperture 14am provided ioo with week day indicating marks 16, there being a sufficient number of such marks 16 to provide seven different combinations for each calendar month. The indicating marks 16 on the top of the aperture 141 do not indicate the same day of the week, respectively, as tlie indicating marks 16 along the bottom of the aperture and that are directly underneath the marks along the top of the aperture, i, e., the indicia along the top of' the aperture begins and ends with Sun. and the indicia along the bottom of the aperture begins and ends with Tue. An adjustable finger 17 is pivotally connected'to the slide 13 and is adapted to cover any one of the last three numbers, viz. 29, 30 and 31, which designate the days of the month as shown in Fig. 5 or such finger may be adjusted as shown, in solid lines Fig. d, to disclose all of the numbers.

The rear piece 2 of the calendar is provided with the chart or table T by which may be determined the day of the week on which the first of each month from the year 1818 to 1997 inclusive, respectively occurs.

The spaces n which are arranged at the longitudinal edges of the calendar, have therein indicia in the form of numerals `designating different years from 1818 to 1997 inclusive. The marks 18 which designate the days of the week are arranged in vvertical columns with respect to the year numbers in thespaces n and in horizontal columns with respect to the marks 19 which designate the various months.

T'o determine on what day of the week any past; present or future date will come one has simply to find lthe required year number in one of the spaces n, then follow up or down, as the case may be, its vertical column of marks 18 until opposite the mark 19 designating the month in which the required date is, and such mark 18 arranged horizontally of the required month will designate the day of the week on which the first of sucli month will come. Then on the front of the calendar adjust the slide 7 so that the required month appears in the aperture 5 which is open to one side of the body of the calendar and likewise move the slide 13 so that the number one of the numerals @will be directly beneath one of the marks 16 at the top of the aperture 14, corresponding to the day mark 18 previously ascertained in the table T.

The day of the week corresponding to the remaining days of such month will be found either above or below the numerals (L representing the days of the month.

Y A star s placed at the head of a year number in the space n designates that the same is a leap year.

For example, in case one desires to find the days of the week corresponding to the days of the month of January 1919, the day of' the week on which the first of January came, may be found by following the vertical column c in which the year l1919 is designated, up to tlie horizontal space d in which the mouth of January is located and determine that the first of January came on llVednesday.

The slide 7 is moved so that the month of January is visible through the aperture 5 as shown in Fig. 4, and as'there are 31 days in the month Vas indicated at 12 the finger will be so positioned as to uncover the numerals a; as shown in Fig. 4. The slide 13 will then be so positioned as shown in Fig. f1 that number one of the numerals a will be underneath Ved. of theeinarks 16. The succeeding weekdays will be found above or below the consecutive days of the month designated by the numerals a.

Should Feb. of 1920 be desired it willpbe seen by the star s that such was a leap year and by following the above method that the 1st of the month came on Sunday, and the slides 7 and 13 will be adjusted accordingly, as shown in Fig. 5.
